Permanently connected appliance rated at not over 300 volt-amperes or 1/8 horsepower.

Branch-circuit overcurrent device where the switch or circuit breaker is within sight of the appliance or is capable of being locked in the open position in compliance with Section E4101.8. Switches and circuit breakers used as disconnecting means shall be of the indicating type.

Permanently connected appliances rated in excess of 300 volt-amperes.

Branch circuit switch or circuit breaker located within sight of the appliance or such devices in any location that are capable of being locked in the open position in compliance with Section E4101.8. Switches and circuit breakers used as disconnecting means shall be of the indicating type.

Motor-operated appliances rated over 1/8 horsepower.

For permanently connected motor-operated appliances with motors rated over 1/8 horsepower, the disconnecting means shall be within sight from the appliance or it shall be capable of being locked in the open position in compliance with Section E4101.8. The disconnecting means shall be one of the following types: a listed motor-circuit switch rated in horsepower, a listed molded case circuit breaker, a listed molded case switch, a listed manual motor controller additionally marked “Suitable as Motor Disconnect” where installed between the final motor branch-circuit short-circuit protective device and the motor. For stationary motors rated at 2 hp or less and 300 volts or less, the disconnecting means shall be permitted to be one of the following devices:

1. 1.

   A general-use switch having an ampere rating not less than twice the full-load current rating of the motor.

2. 2.

   On AC circuits, a general-use snap switch suitable only for use on AC, not general-use AC-DC snap switches, where the motor full-load current rating is not more than 80 percent of the ampere rating of the switch.

3. 3.

   A listed manual motor controller having a horsepower rating not less than the rating of the motor and marked “Suitable as Motor Disconnect.”

The disconnecting means shall have an ampere rating not less than 115 percent of the full-load current rating of the motor except that a listed unfused motor-circuit switch having a horsepower rating not less than the motor horsepower shall be permitted to have an ampere rating less than 115 percent of the full-load current rating of the motor.

Switches and circuit breakers used as disconnecting means shall be of the indicating type.

Appliances listed for cord-and-plug connection.

An accessible separable connector or attachment plug and receptacle.

Permanently installed heating equipment with motors rated at not over 1/8 horsepower with supplementary overcurrent protection.

Disconnect, on the supply side of fuses, within sight from the supplementary overcurrent device, and within sight of the heating equipment or, in any location, where the disconnecting means is capable of being locked in the open position in compliance with Section E4101.8.

Heating equipment containing motors rated over 1/8 horsepower with supplementary overcurrent protection.

Disconnect permitted to serve as required disconnect for both the heating equipment and the controller where, on the supply side of fuses, and within sight from the supplementary overcurrent devices, if the disconnecting means is also within sight from the controller, or is capable of being locked in the open position in compliance with Section E4101.8 and simultaneously disconnects the heater, motor controller(s) and supplementary overcurrent protective devices from all ungrounded conductors. The disconnecting means shall have an ampere rating not less than 125 percent of the total load of the motors and the heaters.

Heating equipment containing no motor rated over 1/8 horsepower without supplementary overcurrent protection.

Branch-circuit switch or circuit breaker where within sight from the heating equipment or capable of being locked in the open position in compliance with Section E4101.8 and simultaneously disconnects the heater and motor controller(s) from all ungrounded conductors. The disconnecting means shall have an ampere rating not less than 125 percent of the total load of the motors and the heaters.

Heating equipment containing motors rated over 1/8 horsepower without supplementary overcurrent protection.

Disconnecting means within sight from motor controller or is capable of being locked in the open position in compliance with Section E4101.8 and simultaneously disconnects the heater, motor controller(s) and supplementary overcurrent protective devices from all ungrounded conductors. The disconnecting means shall have an ampere rating not less than 125 percent of the total load of the motors and the heaters.

Air-conditioning condensing units and heat pump units.

A readily accessible disconnect within sight from unit as the only allowable means.^a

Appliances and fixed heating equipment with unit switches having a marked OFF position.

Unit switch where an additional individual switch or circuit breaker serves as the other required disconnecting means. The following shall be permitted to serve as the other required disconnecting means:

1. 1.

   One-family dwelling—the service disconnecting means.

2. 2.

   Two-family dwelling—an individual switch for the dwelling unit located inside or outside of the dwelling unit.

Thermostatically controlled fixed heating equipment.

Thermostats with a marked OFF position that directly open all ungrounded conductors, which when manually placed in the OFF position are designed so that the circuit cannot be energized automatically and that are located within sight of the equipment controlled.
